Aftermarket Crank Pulley Installation(2.2, 2.4)

[cobalt123]

So i have permmsision from the creator: Jn2 to do it so



Tool needed:
jack and jack stands
serpentine belt tool
air tools(electrical impact works fine too)
sockets set

Materials needed:
MRZ pulley(which ever size u picked)
gatorback p#4050390 belt if you picked the UDP version
silicone
antisieze
motor oil
crank bolt(stock is a TTY)


step 1: jack vehicle in the air and remove the passenger side tire
step 2: remove fender lining if ts in the way(dont remember if i took it off or not)
step 3: use serpentine belt tool to take tension off the tensioner and remove the stock belt, the little hole is located right in the middle of the tensionor
step 4: use you impact to remove the crank bolt, i used a electrical impact rated 200lbs/ft, removed that bolt no questions asked
step 5: once the bolt is out you can wiggle the stock balancer out, i had a harmonic balancer removel tool with me, didnt need it, the stock one came out by wiggling it out, this is what you will see once its out

step 6: put silicone on the keyway on the inside of the pulley, you will know which im talking about when you see it, it looks like something slides in it, next put antisieze on the inside where the bolt will got thru, after that put some oil on the outer part of it to lube up the pulley for when it goes in, you can look at your stock one as it has oil on it too rom the engine

where it says grease, put oil
step 7: wedge the pulley back in the way it came out, only goes one way since it has that slit in it, once its in;

^^thats the UDP installed

^^thats the OEM lightweight installed
step 8: put the bolt back on, and re-trq it on there, this part you will hear alot of, some say you can use it over, some say get a new one, i used the stock bolt, threw 200lbs of trq to it and called it a day, how ever here is the proper specs for it
First pass ……………………...............………100 N-m / 74 lb ft
Second pass …………………..............………75 degrees
step 9: put your belt on, put lining back on, put everything back in

when you start your car it might idle a bit higher, mine idled 1200rpm, i let it sit for a good 15-20 mins and the idle settle back down to 800

It's called a keyway.

[cobalt123]

what is the crank pulley?

[utsadude]

No, the slot area it keeps referring to.

Just fixing a small problem in an otherwise flawless how-to.


Who wrote this up?

[cobalt123]

at the top, JN2 i pm'd him to move it over cuz ima gonna need it, he said he was too lazy to do it, i would otherwise be as well but he said i could move it and i did

[utsadude]

Gotcha.

Oh Juan... For a guy who works on his car every other day, you would think he would know what a keyway is already... haha

[cobalt123]

i see where it said that and replaced with keyway, was it just once

[utsadude]

Too tired to reread... Can't remember how many times I saw it...

[cobalt123]

i did ctrl f and search for slot area, came up once in your post so all done
